As a heavy user of Airbnb, Nuwat still made me surprisingly satisfied. The room itself is big enough for someone who travels alone. Air-conditioner and electric fan are well-equipped. Laundry service with reasonable price. A bike is available to ride around the neighborhood or commute to the MRT station (for free). A currency exchange store named "Ratchada Exchange" with similar rate with "Super Rich" is nearby.
On top of these, Nuwat is always willing to help and did solve some trivial issues during my stay. I would definitely visit Nuwat's place again if I came back to Bangkok in the future. Highly recommended.
